UNITED STATES LUBRICANT-'DISPENSING DEVICE Application mea November29,1927.

The invention relates to a lubricant dispensing device, and has for itsobject to provide a device of this character particularly adapted foruse in garages, and provided with a plurality of receptacles havingpistons therein, which pistons are provided with rack bars, with which arotatable gear meshes whereby upon rotating said gear one piston will be`iforced downwardly, and the other piston simultaneously moved upwardly,whereby when rlubricant is discharged from one cylinder, it may besucked into the yother cylinder for a subsequent dispensing operation.

A further object is to provide a supply pipe leading from a lubricantsupply tank and having branch pipes through either of which lubricantmay be directed to either of the dispensing cylinders. Also to providedischarge pipes leading from the cylinders.

A further object is to form the cylinders from transparent materialwhereby the liquid level therein may be observed, and to provide saidcylinders with graduations whereby the amount oit lubricant in thecylinders may be easily ascertained.

lVith the above and other objects in view the invention resides in thecombination and arrangement of parts as hereinafter set forth,

shown in the drawing, described and claimed,

it being understood that changes in the precise embodiment of theinvention may be made within the scope of what is claimed withoutdeparting from the spirit of the invention. o

In the drawing:

Figure 1 is a front elevation of the device, parts being shown insection to better illustratel the same.

Figure 2 is a side elevation of the device.

Figure 3 is a vertical transverse sectional view through another form ofcylinder wherein a piston is controlled by a piston rod.

Referring to the drawing, the numeral 1 designates a base, which basehas mounted thereon flanged cylinder bases 2 iny which are disposed thelower ends of transparent cylinders 3. Cylinders 3 aref' preferablyformed .trom glass and provided with graduations/l,

ySerial No. 236,457.

whereby they amount, of, lubricant therein maybe jascertained'kkat alltimes'. Disposed on theiupper endsof thecylinders 3 is a4 iiangedcap',,forming a closure Jfor the up-` per endsof ,thecylinders, and slidablymount# ed within the` ,cylindersare pistons `6, which pistons areprovided with upwardly eXt-end-` ing ypiston' rodshaving racks 8 ontheir in# neradjacent sides. yi

r/Eittending upwardly from thejc'api 'is a e0 y bracket 9 in the arms10ho'f which the piston, rods 7` `are slidably mounted, yand rotatablymounted in the upper end ,of thebracket 9 is atransversely disposedshait11 having a gear i; 12 thereon, which geary meshes with the racks 65 8,therefore it will be seen that when the operator graspsfthe handlemember 13 and ro-t tates the gear 12, one of said piston rods andpistons will be forced downwardlyy and at ,l

the same time the other piston andpiston rod 7,0 i

vwill beforcedupwardly, and as a result of this operation lubricantwithin one of the cylinders will beforced outwardly through itsdischarge pipe 14 while lubricant will be sucked into the other,cylinder through the lubricant sup- 5" ply pipes 15 according to whichpiston isornov-k ing upwardlygtheret'ore it will be seen that when thelubricantisdispensed from one cylinder, the othercylinder will beautomatically illed, consequently f a constant lubricant ed supply `ismaintained for dispensing purposes.

Discharge pipes 14 Lare preferablyprovided with Valves 16 .forregulatingthe amount of lubricantand speed of delivery.

Supply rires 115 17 ot' a three way valve 18 and a pipe 19'is connectedto the casing 17 and'leads to a lubricant storage tank 20, and it willbe seen by referring to Figure 1, ysaid three wayr valve y18 W isinposition where upon upward movement of one ot the pistons 6, lubricantwill be sucked into its cylinder 8, 'as the rlubricant is dischargedfrom the other cylinder 3,`and after f the lubricant is discharged fromthe cylinder that is filled, the threeway valve is rnanipu-v latedwhereby lubricant will be'suclred into the emptied cylinder upon upwardmovement of its'piston. The cap 5 is preferably provided with an airvent 21 whereby air may eX-y haust from the upper ends of the cylinders,10o

,PATENT tori-"ICE are connected tothe casingl sa thereby preventing thesame from becoming air bound. Tank 20 is also provided With an air vent22 for allowing passage of air during the filling of the tank and thepumping of lubricant therefrom, thereby preventing the same frombecoming airbound or the formation of vacuum in said tank as lubricantispumped therefrom,

Referring to Figure 3 a hand operated device is shown, Which deviceoperates subst-anv-y tially the same as one ofthe cylinders shown inFigure l and has its piston 6a provided with aV piston rod 7, andwhichpiston rod is adapted to be forced downwardly for discharginglubricant fromwther cylinder 3* through the discharge pipe 14a. In thisform a coiled spring'' is provided Vwhich surrounds the piston rod 7aand is interposed between the a and the piston 61a, thereby assistingwinforcing the piston downwardly for discharging lubricant from thecylinder, From the "aboveit wvill be seen that a lubri cant dispensingdeviceisprovided Which particularly adapted for usel in'dispensinglubricant in garages and the like, and one wherein not only the operatorbut the pur-` chaser may rsee the amountof lubricant *discharged into acrank casing or other point of discharge; 39 The invention having beenset forth What is claimed as newv and useful is :v

` A lubricant dispensing device comprising adjacent cylinders formedfrom transparent material, discharge pipes carried by the lower ends ofsaid cylinders, a lubricant supply pipe,

branch lubricant supply pipes, valve means carried by said supply pipeat its point of connection ivith the branch pipes andfornjing meanswhereby lubricant may be directed Q through either branch supply pipe orsimul- V taneously drained from both of said cylinders, Y

pistons Within said cylinders,'piston rods car-f i'ied by said pistons,said piston rods having their @Climent sides provided Withracls, 45bracket supported by the cylinders, Said pisf ton rods being slidablymounted in bearings of the bracket, and an'operating gear carried bysaid bracket andmeshing with the racks'.
